자주 묻는 질문

Should I use HS256 or RS256 for JWT?

Use HS256 for simple setups where the same server signs and verifies. Use RS256 for microservices where different services verify tokens with a public key.

How long should JWT tokens last?

Access tokens: 15 minutes to 1 hour. Refresh tokens: 7-30 days. Shorter lifetimes reduce the impact of token theft.
